REGULATOR Eon ENGINES.

Specification of Letters I Patent. Patented J an. 13, 1920.

Application filed April 10, 1919. Serial No. 289,109.

, This invention relates to devices for reg ulating engines used for pumping water and otherliqulds into tanks; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed whereb the engine is stopped when the liquid in t e tank rises to a predetermined height.

In the drawings, of a regulating mechanism constructed according to this invention. F ig.'2 is a plan view of the same. v

A tank 2 for the liquid is provided, and 3 is its inlet pipe which is connected to the pump. The pump is of any approved kind, preferably driven by an internal combustion engine, and the pump and its engine are not shown as they are of any approved construction. A suitable stationarlyv support 4 is arranged adjacent to the tan r, or in any other convenient position, and 5 is a catch which is pivoted at its middle part on a pin 6 which projects laterally from the support.

One end portion of the catch has a notch 7 I in its underside, and 8 is an arm which pro? jects upwardly from the other end portion of the catch.

A flexible connection 9, such as a cord, or chain, is secured to the upper end of the arm 8. This flexible connection 9 passes over a guide sheave 10 which iscarried by an arm 12 which projects from the support fl, and it has a float 14 on its .free end which depends within the'tanlc- A catch spring "15 is attached to the same end portion of the catch as the arm 8., andis', :secured to the support 4. The floatis made of such weight that it will hold the catch in the position shown in Fig. .1 with the catch spring extendedand under tension, as long as the float is above the top of the liquid in the tank.

An actuating lever 18 is pivoted to the support 4 by a-pin19, and its free end 20 is pointedand arranged to engage with the Figure 1 is a front view .notch 7 of the catch when in the position shownin Fig. 1. A strong actuating spring 21 is provided, andis secured at one end to the support 4, with its free end portion bearing against one side of the actuating lever 18.- A bumper or stop 24.- projects fromthe support l for the actuating lever to strike against when released from the catch.

An actuating device 26, such as a cord, chain or rod, is connected to the upper end portion of the actuating lever, and is pref- -erably provided with three branches 27,

28 and 29. Thenthe pump is driven by an internal combustion engine, these three branches are connected to the as valve, the electric switch, and the lubricator of the engine, so that all of these parts may be actuated simultaneously.

A cord 30 is also attached to the lever, and may be connected to a hook 31 on the support 4, so as to hold the actuating lever in aninoperative position when the engine is not being used to drive the pump.

When theliquid in the tank rises so that it raises the float, it permits the catch spring to raise'the catch out of engagement with the point 01 the actuating lever, which is then forced over against its stop by the actuating spring, thereby pulling on the actuating device and stopping the engine.

What I claim is;

In an engine regulating device, a pivoted actuating lever operatively connected with the engine, an actuating spring for moving the. said lever pivotally in one direction, a pivoted catch having a notch at one end which normally engages with the said lever and prevents it from bein moved by the actuating spring, said catc having a projecting arm at its other end portion, a tank for liquid, afloat adapted to be raised by the liquid in the tank, a guide sheave, a hexible connection passing over the guide sheave and connected to the said arm at one end and to the float at the other end, and a catch spring which operates the catch and releases the' actuating lever when the float is raised by the liquid in the tank.

In testimony whereof I have afiixed my signature.

"WILLIAM WASHINGTON HILL'.
